Hey O2! Yeah, my school year gets pretty hectic, so I try to get back in the swing of the forum in the summer - when I have the time, haha...

Nice to hear you are having success with the warm whites - my mix wasn't producing the color I was looking for, so I added some red as well. It was a little, but the difference in growth was noticeable.

One thing I think some of us are still tweaking is getting the right spectrum mix to best promote red plants as that seems to be the only issue with LEDs. I get a bit of color with my mix, but I agree with the most in that somethings missing.

How many of these builds use a plexiglas shield? Anyone ever play around with using different types of it? Ie clear, blue, green tint...

Hey Salmon, any progress on this? I have been wondering if anyone had any results fiddling with red LED's to help with coloration. I know a couple people were trying some stuff out, but I haven't heard anything in a while. Let me know if you have updates!

Close to a year of this thread! I hope it has been helpful to folks as you venture into DIY LED's! Feedback on this thread is always welcome. Let me know if there are things that are out-of-date, or updates that could be made. I'm happy to keep this thread current for anyone looking to build a fixture, or just to "nerd out" on the process.

That's an even better idea. Might have to give that a whirl, looks like there's a dealer quite close to me. My fixture might be lacking the punch to get the most out of trying this but it's seems like it could be a great idea to play with as far a tweaking my current spectrum goes.

Thanks for the link hoppy.

I am using Cree XT-E's (50/50 cool white and neutral white) and I get great color - however, I have no real red plants. Using the Rosco gels would be great to see! Some of the guys around here are looking at using more warm whites. Jcgd is one, I believe. I'll keep an eye out and link in what I find as I can!

Feel free to use these 3 (series/parallel/horrible mash) diagrams.

Oh thanks - got it! That is a pretty cool build, actually.

you might also want to add cheiftston's fluval edge build.

Haha, well that's better than a pea shooter in bear country, eh?

thanx!

i guess it's also a cautionary tale of what can happen if you don't pay attention to the threads you use to do your build. i'm loaded for bear when a pea shooter would have done. in light of hoppy's spreadsheet i've dropped the current and the tank looks more natural. your thread should make life a lot easier for the people who come along later.
